One type of aerosol generating system is an electrically powered smoking system. handheld an aerosol generating device comprising an electrically powered electric heater, a battery and control circuits, and Smoking systems comprising an aerosol generating cartridge are known. Some In the examples, the electric heater forms part of the aerosol generating device. However The electric heater may be contaminated with material from the aerosol generating substrate during use. and it may be difficult to clean the electric heater inside the appliance. In some cases the heater is correctly If it cannot be cleaned properly, it may be necessary to dispose of the entire device. other examples by incorporating the electric heater into the aerosol generating cartridge, thus to overcome this problem by discarding it together with the cartridge after use. containing a removable substrate to which a plurality of describes an electronic cigarette smoking product. However, you do not need to clean this heater. Although it is necessary to include a heater in each cartridge, it is necessary to manufacture the system. The cost of doing so increases significantly.

Accordingly, it is essential to manufacture the device and cartridges when addressing the problem of heater contamination. It may be desirable to produce an electrically powered aerosol generating system that minimizes the cost of

An aerosol generating device according to the present invention includes a removable aerosol generating cartridge and An electrically powered aerosol generating system including a removable heater is provided, in which This removable aerosol generating cartridge and the removable heater are separately is provided. The aerosol generating cartridge contains at least one aerosol generating substrate and the heater with at least one electrical heating element and the first electrical heating element connected to this at least one electrical heating element.

Aerosol according to the invention Aerosols produced from the aerosol-forming substrates of they can be invisible and vapors as well as liquid droplets of gases and condensed vapors (For example, a gaseous substance that is normally liquid or solid at room temperature may also contain particles.

As used herein, "substantially flat" means a thickness of at least 12 indicates a component with a width ratio. Preferably this thickness-to-width ratio It is less than approximately 1:20 in order to minimize the risk of bending and breaking of the component.

Advantageously, a substantially flat heater and a substantially flat cartridge This simplifies the insertion of the heater and cartridge into the device. In addition flat components can be easily handled during manufacture. In addition, largely flat and the width, length, or any length of the aerosol-forming substrate of an airflow released from the aerosol-forming substrate when arranged in such a way that it is drawn through both Insert the main cavity, the heater and the cartridge into the main cavity together with the cartridge and the heater. It is beneficial to arrange them in such a way that they are parallel and adjacent to each other when they are taken. It ensures the best contact between the heater and the cartridge, and therefore the heat Maximizes heater-to-cartridge transfer. This arrangement also includes the size of the gap. minimizes and therefore minimizes the overall size of the aerosol generating system. systems according to the invention by providing it as a separable element It also facilitates cleaning of the heater in case of material contamination from the substrate.
